Study Notes

Computer Hardware Components

Central Processing Unit (CPU): The "brain" of the computer, responsible for executing instructions. It performs calculations, manages data, and controls other components. Different types of CPUs have varying clock speeds and core counts, influencing processing power.
Memory (RAM): Random Access Memory, temporary storage for data and instructions currently being used by the CPU. More RAM generally allows for more applications to run simultaneously without slowing down the computer.
Motherboard: A printed circuit board that connects and interconnects all the computer components. It provides the electrical pathways for data transfer and power distribution. Crucial for system stability.
Storage Devices: Include hard disk drives (HDDs), solid-state drives (SSDs), and optical drives (CD/DVD). HDDs use spinning platters, SSDs use flash memory, and optical drives use lasers. Storage devices hold data permanently. SSD speeds tend to be significantly faster than HDDs.
Graphics Processing Unit (GPU): Specialised processor designed for rendering images and videos. GPUs are crucial for tasks like gaming, video editing, and 3D modeling, as they are considerably faster at these tasks than CPUs.
Input Devices: Devices that allow users to interact with the computer, such as keyboards, mice, touchscreens, and scanners. Keyboards and mice are common input devices for text entry and navigation.
Output Devices: Devices that display or present information from the computer, such as monitors, printers, and speakers. Monitors display visual information, printers create physical copies, and speakers produce audio.
Power Supply Unit (PSU): Converts AC power from the wall outlet to the lower DC voltages required by computer components. Ensures proper power delivery, preventing component damage.
Expansion Cards: Boards that can be added to the motherboard to expand computer functionality. Examples include sound cards, network cards, and video cards. Adding these cards enhances specific computer capabilities.
Cooling Solutions: Crucial components that help regulate component temperatures. These include fans and heatsinks, and are necessary to prevent overheating.

Types and Characteristics of Storage Devices

Hard Disk Drives (HDDs): Use spinning platters and read/write heads to store data. More affordable than SSDs but significantly slower. Data is organized in the form of tracks and sectors.
Solid State Drives (SSDs): Use flash memory for data storage. Faster and more durable than HDDs but potentially more expensive. Often used in laptops and high-performance desktops.
Optical Drives (CD/DVD/Blu-ray): Use lasers to read and write data on optical discs. Less practical for everyday storage but are commonly used for backups and distribution of files. The storage capacities vary depending on the disc type.

Computer Hardware Performance Metrics

Clock Speed: Measures how fast the CPU can execute instructions, usually measured in GHz. Higher clock speed generally implies faster processing.
RAM Capacity: The amount of RAM a computer has determines the number of applications that can run simultaneously without slowing down. Higher RAM capacity supports more programs to run efficiently.
Storage Capacity: The total storage capacity of a computer impacts how many files, applications, and programs can be accommodated. Measured in GB or TB.
GPU Performance: Measured in terms of processing speed, the number of cores, and memory capacity. High GPU performance is vital for graphics-intensive tasks.

Other Important Hardware Considerations

Form Factors: The physical size and layout of computer components. Common desktop form factors include tower and mini-tower cases. Laptops have their own form factors.
Connectivity: Includes ports like USB, HDMI, Ethernet, and Thunderbolt. These ports allow for connecting various devices and peripherals.
Compatibility: Ensure hardware components are compatible with the motherboard and other crucial components to avoid compatibility issues.
Heat Dissipation: Proper cooling is necessary to prevent overheating, vital for consistent performance and preventing component damage.

Future Trends in Computer Hardware

Advancements in CPU Architecture: CPUs are becoming more efficient and powerful, often featuring multiple cores and advanced instruction sets.
Increased SSD Adoption: SSDs are expected to become even more prevalent as storage technologies continue to evolve.
Development of Specialized Hardware: Hardware is becoming more specialized for specific tasks and applications, including dedicated AI chips and accelerated computing units.
Improved Power Efficiency: Hardware components are increasingly focusing on energy efficiency.
